**What is the half-width of the confidence interval**

I have a small doubt regarding a statistics problem and would like a confirmation. If we want to reduce the length by half of the confidence interval (at 95%), we should: Multiply the size of the... Confidence Level, Sample Size, and Width of Interval The confidence level you choose will determine how confident you can be that your interval captures the population parameter. The most common confidence levels used are 90%, 95%, and 99%.

## How To Find The Half Width Of A Confidence Interval

Half-Width of Confidence Interval for Normal Distribution Mean or Difference Between Two Means Description. Compute the half-width of a confidence interval for the...

- When sample.type="two.sample", the computed half-width is based on a confidence interval for the difference between two proportions. The default value is sample.type="one.sample" unless the argument n2 or p2.hat is supplied.
- In order to obtain the half-width of a confidence interval, the alpha value, population standard deviation and sample size have to be entered in succession in the dialog box shown below.
- When sample.type="two.sample", the computed half-width is based on a confidence interval for the difference between two proportions. The default value is sample.type="one.sample" unless the argument n2 or p2.hat is supplied.
- Hence keeping with 95% confidence, you need a wider interval than you would have needed with a larger sample size in order to be 95% confident that the population mean falls in your interval. After you calculate a confidence interval, make sure you always interpret it …
